Title: The Innovations of Shir-Kuan Lin
Introduction
Shir-Kuan Lin is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced voltage generating apparatuses and motor driving methods. With a total of 3 patents to his name, Lin's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
One of Lin's latest patents is a gamma voltage generating apparatus designed to produce interpolated gamma voltage. This invention includes an operation amplifier, reference impedance units, variable impedance units, and a select unit. The operation amplifier generates an amplified output voltage, while the reference impedance units receive specific gamma voltages. The select unit plays a crucial role in determining whether to use the amplified output voltage or the first gamma voltage based on a control signal, ultimately generating an interpolated gamma output voltage.
Another significant patent by Lin is a sensorless driving method for brushless DC motors. This method involves counting zero crossings with two counters to determine the time for the motor to rotate an electrical angle of 60 degrees. By delaying the motor's rotation by an electrical angle of 30 degrees, Lin's method achieves precise commutation timing. The driving method also incorporates a mask-based phase shift digital detection mechanism to effectively identify true zero-crossing points, along with a soft-switch function to minimize noise during transistor switching.
